[AccessD] Machine Transfer Issue

I had an xp mdb running on an xp os machine to clients satisfaction.
 
The database was split for development and upgrades
 
The IT contractor who hired me put a new machine in the clients office.
 
Here it comes:
 
The clients home drive is on the network now
 
The database can not find 2 sub tables so many forms and reports are now
failing.
 
There is a tape back up we could go to.
 
It is the second on 2 identical databases on the same machine for 2
different divisions of the company.
 
I thought maybe I had left the tables in question pointing at the original
data database but that was not the answer.
 
Short of the tape anyone have an idea?
 
 
Thanks
 
Joe
